How UK property valuations work
Property valuations in the UK are based on comparable evidence — what similar properties in the same area have sold for recently. Estate agents, surveyors, and automated valuation models (AVMs) all use this approach. The key variables are location (down to street level), property type, size, number of bedrooms, condition, and tenure (freehold or leasehold).
Land Registry records every residential sale in England and Wales, typically within 3–6 months of completion. This tool draws on that data to identify recent comparable sales near your property and produces an AI-generated estimate that accounts for differences between your property and the comparables found.
Factors that affect property value
Beyond the headline figures of size and bedrooms, a property's value is influenced by its condition, EPC rating, garden, parking, local amenities, school catchments, transport links, flood risk, and the specific street. Two identical houses on the same road can command different prices based on aspect, proximity to a school, or whether one has been extended. This tool's optional description field lets you provide detail about features that the basic data wouldn't capture.
For leasehold properties, remaining lease length significantly affects value — properties with fewer than 80 years on the lease face a "marriage value" premium to extend, which can substantially reduce their market value. Indicate your tenure so the valuation can account for this.
Frequently asked questions
What data does this valuation use?
The valuation is based on Land Registry sold price records for England and Wales. The AI reads the recorded sales in your postcode, weighing those of your property type (the register does not record bedrooms), then adjusts for differences between your property and those comparables. The description field lets you provide additional context (condition, features, extensions) that the basic data wouldn't capture.
How accurate is an AI valuation?
AI valuations are indicative estimates, not precise figures. What decides how good one is, is the evidence underneath it: how many sales of the same property type your postcode recorded in the last three years, and how alike they are. Every valuation shows the comparables it used, so you can judge the estimate rather than take it on trust. Where there are fewer than three such sales, we say so and state no figure. For unique properties, or in quiet markets, expect a wider range.
How is this different from a RICS valuation?
A RICS Red Book valuation is a formal assessment by a qualified surveyor who physically inspects the property and produces a legally compliant report. It is required by mortgage lenders. This tool provides an indicative estimate for research purposes only — it is not a formal valuation and cannot be used for mortgage, legal, or insurance purposes. For those, consult a RICS-registered surveyor.
Is there a limit on how many valuations I can get?
Yes — the tool is rate-limited to 5 valuations per IP address per 24 hours. If you need more, try again the following day. For a Pro report — fair value from comparables where the sold evidence supports one, and survey questions with conditional repair budgets — compare one on a composite home at homethink.co.uk/pro/sample, then subscribe if it is worth it to you.
Do I need to create an account?
Yes. This tool is part of HomeThink Pro, so you need a Pro account. Enter your property details and get an instant AI valuation. Look up any home by postcode and address for a Free report — crime, flood, EPC and sold prices included — and see a real Pro report, with fair value from comparables where the sold evidence supports one, at homethink.co.uk/pro/sample.

An estimate, not a professional valuation. For a mortgage or for legal purposes you will need a RICS-accredited surveyor.
